Write a function called triangle that takes in two parameters: b and h that represents the base and height respectively. The function calculates and returns the area of the triangle. You may assume that the arguments passed into the function are valid base and height values.

Sure, here's how you can write this function in Python:

1. First, we define the function using the def keyword, followed by the function name triangle. In the parentheses, we specify the parameters b and h, which represent the base and height of the triangle, respectively.

def triangle(b, h):

2. Inside the function, we calculate the area of the triangle. The formula for the area of a triangle is 1/2 * base * height. We use the * operator for multiplication and the / operator for division.

    area = 0.5 * b * h

3. Finally, we use the return statement to specify that the function should return the calculated area.

    return area

4. Putting it all together, the complete function looks like this:

def triangle(b, h):
    area = 0.5 * b * h
    return area

5. Now, you can call this function with the base and height values to get the area of a triangle. For example:

print(triangle(10, 5))  # Outputs: 25.0

In this example, the function calculates the area of a triangle with a base of 10 and a height of 5, and then prints the result, which is 25.0.
